The present invention relates to a clip removing device and more jparticularly to a device j adapted to serve'as an accessory to a cloth finishing machine for removing any clips which may be attached to the edge of the cloth passing therethrough.

g In the performance of textile finishing processes it is ordinarily the custom to pass the cloth being treated through any of several types of I machines depending upon the particular treatment desired and then either to reroll the cloth on a mandrel or pass it in loose folds into a box spring metal clips over both edges of the cloth Ordinarily these spring cloth only longenough to carry the cloth through the particular process where curling takes place. At the conclusior of this process it is necessary to remove all of the clips so that they do not cause damage in some further process.

So far as I know, clips of this type are in wide use and their use is well understood. In general, these clips are simply narrow strips of sheet metal which are bent at approximately the central point through an angle of 180 degrees so that the clip forms two parallel arms which are spring pressed against each other. These clips are of the order of two inches long or so and are simply slipped over the edge of the cloth by an operator at intervals so as to straighten out the curl inherent in the cloth. So far as I know also, it has always been customary to have an operator remove these clips manually and it has been my experience that frequently the operator will overlook some of the clips which later find their way into subsequent processes and therefore cause damage to the finishing machinery or damage to the cloth being treated.

In view of the above it is the primary objective of the present invention to provide a simple device which may be attached to a cloth finishing machine wherever its use is desirable, this device serving automatically to remove any clips which are attached to the edge of the cloth passing through the machine.

Yet another object of the present invention is to provide a novel clip removing device of the character indicated which may be manufactured at low cost and which may be placed in and out of operation quickly and without difficulty.

2 Claims. (C l. 26-1) Other objects and advantages will become apparent from the following description of a preferred embodiment of my invention.

In the accompanying drawings, in which similar characters of reference refer to similar parts throughout the several views: Fig. 1 may be considered as a front elevation of the clip removing devices as seen when looking in the direction of movement of the cloth through the machine;

Fig. 2 is a top view thereof;

Fig. 3 is a front elevation of one of the cli removing devices drawn to larger scale; and i V Fig. 4 may be considered as a vertical sectional view therethrough taken in the direction of the arrows substantially along the line 4-4 of Fig. 3.

My clip removing device comprises a bracket or post l0 made of round machine steel or the like, the lower end of which is threaded as at ii -mover is to be attached. Thebracket is shown in the drawings as being somewhat goosenecked but the exact shape of the bracket will, of course, depend upon the machine it is intended to fit.

Although clips of the type described are in general used during cloth finishing processes wherever the cloth has a tendency to curl and where this curl needs to be removed before passing the cloth through the processing machine, such clips probably are most often used during calendering operations. A calendering machine is of the nature of a large ironing machine in which the cloth is passed between heated rolls. The clips are normally placed upon the cloth before the cloth reaches the rolls and are removed after the cloth has passed through the rolls. The stanchions referred to will be found at frequent intervals upon machines of this character for the purpose of journaling the rolls or for other purposes. If desired, special brackets which will suggest themselves may be attached to the machine frame at any appropriate point. The upper end of the bracket I0 is threaded into or otherwise secured to a plate M which is disposed in a generally horizontal position and extends transversely of the finishing machine to underlie the edge of the cloth being processed. At a point adjacent the place of attachment to the bracket Ill, plate 14 carries a pair of upstanding side plates It, the upper ends of which are pivoted y pin 8 to one and of a second hurlzontal steel plate 20. The plate 2|! is dispose generally parallel to the plate I 4 and is spaced,

therefrom a matter of something over an inch or so. The free end of the plate 20, however, which overlies the cloth 22 being processed is free to move up and down about the pivot point established by the pin [8.

Each of these plates is provided on the adjacent surfaces with a layer of composition friction material 24 for which purpose 1 have successfully made use of ordinary automobile brake lining material. This material is fastened to the upper and lower faces of the plates l4 and 20, respectively, by countersunk machine screws 2.5 which are passed through the brake lining material and are threaded into the plates J4 and Z- 5.0 as t s e he b ke lining aterial ri idly in place. The spacing between the plates [4 and is such that when the friction blocks 24 are in place and are in face to face contact the plates or strips I4 and 20 are substantially parallel.

The front and back edges of the plates l4 and 20 carry angle brackets 28 and 30, respectively, which project horizontally and. have vertical p s thcrethro gh in alignment. A machine bolt 32 is passed upwardly through. the opening in each of the brackets 28-and through the similar opening in the brackets 30 and above the bracket 30 each is provided with. a coil spring 34,. a washer 36 and a wing nut 38,- By tightening the. win nuts 38, therefore, the degree of compression of the springs 34 can be determined and hence the pressure between the adjacent faces of the friction blocks 24 can be adjusted.

In use, one of these clip removing devices is mounted on a cloth finishing, machine at each side thereof and the edge of the cloth 22 to be processed is located between the opposing faces of the friction blocks 24 after which the wing nuts 38 are adjusted so as to apply a comparatively light but appreciable pressure on the two sides of the cloth 22. Themachine is then placed in operation and it will be appreciated that whenever the cloth passing between the blocks 24 carries clips at its edges, these clips will be brought against the vertical faces of the blocks 24 and thereafter will slide relative to the cloth until they work to the edge of the cloth and fall off. They therefore are removed from the cloth in a simple and efiicient manner without attention.

If some particular textile being passed through the machine does not have a pronounced tendency to curl and therefore clips need not be used to prevent curling, the clip removing devices can placed out of operation simply by loosening the wing nuts 38 so that substantially no pressure is applied to the cloth or, if desired, the plate 14 may be secured to the bracket 10 by a swivel connection so that the operating head of the device can be swung to one side out of the path of movement of the cloth.

Having described my invention, what I claim as new and useful and desire to secure by Letters Patent is:

1. In a clip removing device for use with textile finishing machines the combination comprised of a bracket adapted for attachment to a finishing machine adjacent the edge of the textile material passing therethrough, a head supported upon said bracket in general alignment with the plane of the cloth passing through said machine, said head including a pair of friction shoes adapted to be arranged in contact with the two faces of the cloth adjacent the edge thereof and overlapping said edge, means supporting said friction shoes from said bracket in pivotal relationship so that one of said shoes can be moved toward or away from the other, and resilient means for urging said shoes toward each other.

2. A device for removing spring metal clips from the edge of a web of textile material passing through a textile finishing machine which comprises a pair of friction shoes adapted to engage the two faces of said web at one edge thereof, resflient means for urging said shoes toward each other, and bracket means for attachingsaid' shoes to the frame of said finishing machine.
